Hi there!
Looks like a lot of work is going on here.
Let's start by solving this equation for the x.

Step 1) Add -20y to both sides.

Step 2) Divide both sides by 5.


Final Answer:

Now, let's solve for y.
Step 1) Add -5x to both sides.

Step 2) Divide both sides by 20.


Final Answer:

Hope this helps! :D
Hint - When you have two variables in an equation, and you want to solve for one, the other will end up in your answer. :)

Hello,
2(l+w)=78
Divided 2 from both side
2(l+w)/2=78/2
l+w=39 feet
l=6w+4
Replace l with 6w+4
6w+4+w=39
7w+4=39
Subtract 4 from both side
7w=35
Divided 7 from both side
w=5 feet
l=6w+4
l=6(5)+4
l=30+4
l=34 feet. As a result, the length of the rectangle is 34 feet and the width of rectangle is 5 feet. Hope it help!
